Unfortunately, the problem happened again - even though your patch was applied and XHCI_MAX_HALT_USEC set to 50000. I did get some new debug output [1], though (apparently, this only shows up after some additional timeout has elapsed, so I missed it earlier when rebooting too fast): ... xhci_hcd 0000:0d:00.0: Poll event ring: 4308439040 xhci_hcd 0000:0d:00.0: op reg status = 0xffffffff xhci_hcd 0000:0d:00.0: HW died, polling stopped.
